169.254 ip address - Make it go away

Sebboh · Post by **Sebboh** » April 6th, 2005, 8:46 am

The reason i can't get online is because i have a 169.254.xxx.xxx address engraved on my pc (not literally). Apparently, this address blocks all incoming traffic on windows opperation systems after NT (so NT, ME, xp). Bussiness offices use it on pcs they want to access their business network but not the internet.

I can't quite figure out how to make it go away. It's happening to my pc with xp and my bro's pc with ME, when they're plugged individually into the modem. My mom's pc can get on the net fine thru the modem but not the router (which seems to be the root cause of this). The best way to explain this is to give two examples of what is happening:

My pc -> Router = 169.254 ip address, can't access the internet or recieve any incoming traffic (can't even dial into the router.

My pc -> Cable modem = 169.254 ip address, same as above.

Mom's pc -> Router = 169.254 ip address, see above.

Mom's pc -> cable modem = normal ip address, get's on the internet fine.

Stuff I've tried (on my pc which has xp home):

power cycling the modem
power cycling the router
Deleting my ethernet card out of device manager, rebooting, and reinstalling drivers
fucking with the control panel a lot
making my router local ip (192.168.1.1) the static ip address (still can't get online or even onto the router CP).

Ideas? I know some of you are tech savvy so help me! Please.[/list]

In your router configuration, change the beggining IP adress your router sends out. That was my biggest problem w/ my router, for some reason it was giving the first computer on our LAN the same IP address as the modem.

I've been getting problems like this on and off for the past month. For some reason turning off the router for 30 seconds to let it reset fixes it for me.

but i can't even dial into my router cp because this IP on MY PC is blocking all incoming traffic to my pc from anything outside of my ethernet card.

So access the router from the computer that can access the internet.

That one should have access to the router.

That works when it's a router side problem because unless you have the IP address reserved for your terminal it will cycle what IP is assigned to what terminal on power on (likewise each time it connects/disconnects, which is why I can't get my freaking iBook to hold a static IP).

Isn't there something in NT that stores what IP you were assigned last? I could be misremembering...

Got home from work and its happened again, new computer can't connect to the internet or the router.

Resetting the modem/router doesn't help, help! QQ

FIRST:

Have you used this router before as a router? Are you sure it isn't a switch?

IF IT IS INDEED A ROUTER AND YOU HAVE USED IT AS SUCH BEFORE:

1. Press Start->Run
2. Type cmd
3. Press ok
4. in the dos prompt type (without quotes) "ipconfig /release" and press enter
5. still in the dos prompt type (agains without quotes) "ipconfig /renew"
6. see if you get a legit IP.

IF IT SEEMS TO JUST BE A SWITCH:

This is a little tricky. You need 2 network cards in the computer the cable modem is next to. You will have modem-computer with one of the cards, and computer-switch with the other card.

Get the internet all working on that computer

Identify which of your LAN connections in windows is the one to the cable modem.

Go into it's properties

Go to the advanced tab.

Chack the box for "share this connection" or something like that.

Now that computer will act as a router and assign IP's to the other computers connected to the switch, and they should all happily get internet.

just to clear some stuff up, I am using a ROUTER that I've used in the past and have been using for a long time.

When I plug the pc that can connect to the internet into the router, all incoming traffic becomes blocked, preventing me from trying to access the router as well on that pc.

Thanks for the suggestions :)

I've been looking around on the internet and I think I might have found a solution. Apparently this problem can be solved by reinstalling the tcpip protocol, however, on xp and ME, microsoft decided to make it a system component making it nearly impossible to reinstall it by conventional means. Someone created a tool to do it for you however, which I will try when I get home tonight. Here is the link to the tool and instructions how to make it work:

Here is what I would check to troubleshoot:

1) Make sure that your cable modem is plugged into the right port on the router. Your cable modem should be plugged into a port labelled WAN or Internet. Your PC's should be plugged into the numbered ports on the router, typically 1 through 4.

2) try statically setting the IP address. To do this, go
Start -> Control Panel -> Network Connections (This will open a window with your listed network connections. )
Right Click on "Local Area Connection" and choose "Properties" from the drop down menu.
In the next window that pops up, Double Click on "Internet Protocol (TCP/IP)"

Now here's the somewhat tricky part. You need to know what your router's IP Address scheme is. I will list the ones I know off-hand.

If you have a Linksys router (most common) do the following:
Check the circle next to "Use the following IP address:" and enter in the following information in the corresponding boxes.
IP Address: 192.168.1.8
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1

Now check "Use the following DNS server addresses:"
Preferred DNS server: 192.168.1.1
Alternate DNS server: <leave blank>

Click OK
Click OK
Test the internet. If this works, you can leave it like it is and your machine will run great. If not, post here and we'll try some other things.

If your router is SMC, use this information in those boxes:
IP Address: 192.168.2.8
Subnet mask: 255.255.255.0
Default Gateway: 192.168.2.1
Preferred DNS server: 192.168.2.1
Alternate DNS server: <leave blank>

Another common ip address scheme if the other two don't work is:
IP Address: 192.168.0.8
Subnet mask: 255.255.255.0
Default Gateway: 192.168.0.1
Preferred DNS server: 192.168.0.1
Alternate DNS server: <leave blank>

3) Another good trick is the ultimate hard reset (for those of us who are really anal in the industry)
Unplug your router from power (at the back of the router, not the plug from the wall plug) and wait 30 seconds
plug it back in.
hold down the reset button for 10 seconds (usually with a pencil)
wait until lights settle down so it looks like it's running normally
unplug again and wait 30 seconds
plug it back in
reboot computer
test internet

Never give up. someone will figure it out.

You have any buddies with routers you can borrow to test? Your's might be jacked.

linksys had me set the ip statically when i was on the phone with them, didn't work. The router is plugged in correctly. I'll try doing your clean reboot suggestion but i doubt it works. Anyways, thanks for the help, cyall in a few days
